Metering AC power and energy put us to new challenges when compared to DC. Lets first assume a resistive load where current and voltage are always in phase. If we sample with a frequency lower than double line frequency (eg. 100 Hz), we’ll get aliasing noise. For energy metering this noise doesn’t pose a problem ..
Protective Earth Hazard As many cheap inverters from China, it uses a capacitor voltage divider to create a „neutral“ ground. This ground is in fact just centered between the 2 output wires using a capacitive voltage. This poses the problem that current can flow through the ground wire undetected by fuses or other protection components. ..
